Description

Technical Field

[0001] The utility model relates to the technical field of ground earthquake resistance, in particular to a ground earthquake resistance deformation joint structure device. Background Art

[0002] An anti-seismic joint refers to a special structural measure taken during the structural design or construction of a building to enhance its anti-seismic ability during an earthquake. It is a gap between the internal and external components of a building or an expansion joint set separately. It reduces the transmission and damage of seismic forces by assuming fracture strain and displacement during an earthquake. Anti-seismic joints can be divided into horizontal anti-seismic joints and vertical anti-seismic joints.

[0003] In Chinese Patent No. 202022685631.5, the utility model discloses a ground seismic deformation joint structure, which relates to the technical field of deformation joint structures. The structure comprises a left floor and a right floor arranged on the same horizontal plane, with a gap between the left and right floors forming an installation joint. The top surface of the left floor is provided with a left deformation structure, and the top surface of the right floor is provided with a right deformation structure. The tops of the left and right deformation structures are both provided with a base plate. The bottom of the base plate is provided with a buffer reinforcement structure connecting the left and right deformation structures. The buffer reinforcement structure includes: a support rod arranged vertically on the bottom surface of the base plate; a buffer plate fixed to the support rod and capable of sliding; and an elastic component arranged below the buffer plate and sleeved on the support rod. The utility model has the advantages of high structural strength, good buffering performance, and strong deformation resistance.

[0004] The existing ground seismic expansion joint structure device has a seismic expansion joint directly in the concrete foundation. The expansion joint lacks support for the concrete foundations on both sides. Over time, under the action of lateral pressure from the foundations on both sides, the concrete foundations on both sides of the seismic expansion joint may collapse toward the middle of the seismic expansion joint. In addition, the waterproof layer set in the existing seismic expansion joint is usually a downwardly concave waterproof layer. The moisture that penetrates from the gap in the top bottom plate is easy to accumulate above the concave waterproof layer. Although it will not flow into the seismic expansion joint, the penetrated water accumulates on the waterproof layer and cannot be discharged, which will generate a downward pressure on the waterproof layer. After a long time, it is easy to cause deformation or rupture of the waterproof layer, affecting the waterproof effect.

[0005] Therefore, in order to solve the above problems, a ground seismic deformation joint structure device is proposed. Utility Model Content

Although it will not flow into the seismic deformation joint, the penetrated water gathers on the waterproof layer and cannot be discharged, which will produce a downward pressure on the waterproof layer. After a long time, it is easy to cause deformation or rupture of the waterproof layer, affecting the waterproof effect.

[0029] See also Figure 4 As shown, a ground seismic deformation joint structure device, the deformation joint waterproof component 3 is used to waterproof the seismic deformation joint, the top support plate 302 is in the shape of an upward arch, and the material of the top support plate 302 is set to alloy steel. The materials of the bottom waterproof layer 301 and the top waterproof layer 303 are both set to polyester film material. The bottom end of the top waterproof layer 303 is embedded into the side concrete layer 5 to a depth of eight centimeters. The bottom waterproof layer 301 laid on the inner wall of the seismic deformation joint is convenient for separating the cavity in the middle of the deformation joint from the adjacent side concrete layer 5, so as to prevent moisture in the side concrete layer 5 from penetrating into the seismic deformation joint. The arc-shaped top support plate 302 is provided at the top of the seismic deformation joint, which can support the top waterproof layer 303 in an arc shape, so that moisture penetrating from the top cannot accumulate on the waterproof layer, so that the moisture can be promptly diverted to the side concrete layers 5 on both sides, keeping the internal environment of the seismic deformation joint dry, and protecting the structure inside the seismic deformation joint from corrosion caused by blisters.

[0030] See also Figure 5As shown, a ground seismic deformation joint structure device is provided. The decorative floor assembly 4 is used to weaken the impact force or extrusion force between the decorative base plates. The second decorative floor 403 forms an elastic structure with the first decorative floor 401 through a buffer block 402, and the material of the buffer block 402 is set to be a silicone material. The shape of the connecting block 405 is set in a "U" shape, and the connecting block 405 forms a sliding structure with the first decorative floor 401 through a first slider 404, and the connecting block 405 forms a sliding structure with the second decorative floor 403 through a second slider 406. The buffer block 402 made of silicone material can buffer the first decorative floor 401 and the second decorative floor 403 in the event of an earthquake, so as to convert the kinetic energy of the impact force between the first decorative floor 401 and the second decorative floor 403 into elastic potential energy, thereby reducing the situation where the floor is squeezed and deformed by the impact force.

[0031] Working principle: First, in the absence of an earthquake, this device is in a static state and is set in the foundation. The U-shaped support plate 201 made of carbon steel can provide a supporting force for the side concrete layers 5 on both sides, so as to prevent the side concrete layers 5 from tilting or collapsing toward the middle position of the seismic deformation joint due to their own lateral earth pressure, and the moisture inside the side concrete layers 5 is blocked by the impermeable bottom waterproof layer 301 and cannot penetrate into the middle position of the seismic deformation joint. The moisture that penetrates through the gap of the decorative plate on the top of the seismic deformation joint is blocked by the top waterproof layer 303 and cannot penetrate into the interior of the seismic deformation joint. Under the support of the top support plate 302, the top waterproof layer 303 is in an upwardly arched arc state. When moisture penetrates above the arc-shaped top waterproof layer 303, it will penetrate to both sides along the downwardly inclined sides of the top waterproof layer 303 and finally penetrate into the inside of the side concrete layers 5 on both sides;

[0032] When an earthquake occurs, the side concrete layer 5 on one side may move under the action of the earthquake, and at the same time, an inward squeezing force is generated on the U-shaped support plate 201. The U-shaped support plate 201 is squeezed and deformed by the huge force. At the same time, the second circular gasket 209 is forced to move toward the direction of the first circular gasket 204, and the spring 210 is forced to shrink and change its shape, converting the kinetic energy received from the outside into elastic potential energy, thereby absorbing and storing part of the energy and preventing the object from changing too much in an instant. In this way, the U-shaped support plate 201 can maintain a relatively stable motion state for a period of time, avoiding overreaction and damage. The concrete layer 5 on one side can also be cushioned by the impact force brought by the earthquake on the other side. At the same time, during the earthquake, when the second decorative floor 403 impacts the first decorative floor 401 along with the concrete leveling layer 6 at its bottom, the buffer block 402 made of silicone material can convert part of the kinetic energy brought by the impact force into elastic potential energy, thereby reducing the impact of the second decorative floor 403 on the first decorative floor 401. At the same time, when the second decorative floor 403 moves, the connecting block 405 will slide at the bottom of the first decorative floor 401 and the second decorative floor 403 through the first slider 404.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
